The 13-inch models feature the new dual-core Intel Core i5 or the dual-core Intel Core i7 — the fastest mobile dual-core processor available. Built on a new 22-nanometre process, Intel’s third-generation Core architecture keeps the processor, cache, graphics processor and a faster-than-ever 1600MHz memory controller on a single chip. Since data doesn’t have as far to travel, you can fly through demanding tasks like editing HD video, compiling audio or rendering a multi-layered image file.
